Description

Olfactory sensitivity detector

Technical Field

The invention relates to the field of olfactory detection, in particular to an olfactory sensitivity detector.

Background

The sense of smell is a sensation. It is involved in two sensory systems, the olfactory and nasal trigeminal systems. The sense of smell and taste will integrate and interact. Olfaction is a prerequisite for the realization of pheromone communication. The sense of smell is a sense of distance, meaning that it is a sense of sensing a chemical stimulus over a long distance.

Some people think that the olfactory function has little influence on human health, so that the olfactory health care is usually ignored, and even if the olfactory function is lost, the attention is not paid. Actually, the loss of olfaction is not an independent disease, and is mostly caused by accidents such as external force and strong impact or some diseases, and may be an early symptom of intracranial lesions or psychogenic diseases, so it is not ignored. At present, in physical examination, the smell detection is limited to smelling and smelling, and the smell sensitivity of a detected person cannot be detected, so that the use limitation of the device is large.
